Luminance adjustment system, display system, moving body, and luminance adjustment method

Abstract

A luminance adjustment system adjusts luminance of image display in a display device. The luminance adjustment system includes a controller that changes the luminance in accordance with a value of illuminance in a target space, The controller has, as operation modes, a gradual change mode in which the luminance with respect to the value of illuminance is changed in a first time, and an abrupt change mode in which the luminance with respect to the value of illuminance is changed in a second time being shorter than the first time. The controller makes switching from the gradual change mode to the abrupt change mode with a sign of an abrupt change in illuminance in the target space taken as a trigger, and then operates in the abrupt change mode for at least a fixed time after the switching.
